Removable Magazine Spring Retainer

ABSTRACT

A firearm ammunition clip or magazine which includes a Removable Magazine Spring Retainer for the ease of loading and unloading cartridges into a magazine and allows the magazine to be loaded from the bottom vise the top. The Removable Magazine Spring Retainer contains a follower, bottom and spring for easy insertion into the magazine container to complete the magazine. The Removable Magazine Spring Retainer allows for the cartridges to be loaded from the bottom of the magazine and or while the magazine is inserted into the firearm. This allows the magazine to be compliant with state magazine laws for states that don&#39;t allow removable magazines.

FIELD OF THE INVENTION

The present invention relates to loading and unloading an automatic orsemi-automatic firearm magazine. More particularly, the invention isdesigned to make loading cartridges into a firearm magazine easier andmore efficient without having to use a cartridge loader.

BACKGROUND

Firearm magazines are used in conjunction with semi-automatic andautomatic firearms and are used to deliver cartridges to the firearm.Magazines are designed to hold multiple cartridges in many capacitiesand many cartridge sizes. The ease and speed of loading cartridges intoa magazine appeal to police, military, target shooters and hobbyistswhen loading multiple cartridges.

A firearm magazine is used for the storage and feeding of cartridgesinto a firearm. The magazine includes a housing that holds thecartridges in a position that allows the firearm to load cartridges intothe breech of a firearm. A typical magazine includes a follower thatguides the cartridges through the magazine chamber and into the breechof a firearm. A magazine also includes a spring that is compressed whencartridges are loaded and elongated when cartridges are fired. Thecompressed forces of the spring on the follower push the cartridges upand cartridges can only be loaded one at a time and from the top of themagazine.

Traditionally firearm magazines are loaded from the top by applyingpressure to each cartridge one cartridge after another. After eachcartridge is loaded the spring resistance gets harder and harder as eachcartridge is loaded into the magazine. This spring resistance becomespainful on the loaders fingers and many people can't load the maximumcartridges into the magazine due to the spring resistance.

After the cartridges have been loaded into the magazine and the magazineis loaded into the firearm the compressed internal spring of themagazine forces each cartridge into the firearm breech while the firearmis being fired.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide anammunition magazine for a firearm including a Removable Magazine SpringRetainer that allows for easy loading and unloading of cartridges into amagazine.

It is another object of the present invention to provide an ammunitionmagazine for a firearm including a Removable Magazine Spring retainerthat can be removed from the magazine to quickly load or unloadcartridges.

It is a further object of the present invention to provide an ammunitionmagazine for a firearm including a Removable Magazine Spring retainerthat can be removed from the magazine while the magazine is stillinserted into a firearm. This allows the magazine and firearm to beloaded while the magazine is still inserted into the firearm.

As cartridges are fired from the firearm, unfired rounds are taken fromthe top end of the magazine into the chamber of the firearm while emptyammunition cartridges or shells are ejected from the firearm. Thefollower therefore moves upward under the force of the spring. Theremovable spring retainer comes out of the bottom which allows the userto load and unload the cartridges into the bottom for a quicker and lesspainful way to load a magazine. The removable magazine spring retaineris comprised of 3 pieces: the follower, the spring and bottom piecewhich are inserted into the bottom of the magazine along withcartridges. Once the magazine is loaded with cartridges the removablespring retainer is inserted into the bottom and the base plate is thenslid onto the magazine's existing grooves.

DETAILED DESCRIPTION OF THE DRAWINGS

To traditionally load a firearm magazine, you need to load one cartridgeat a time and apply pressure to the follower and spring to the magazine

FIG. 1 is a view of a rifle (1) magazine which is fully loaded withcartridges. It shows how the Removable Magazine Spring retainer (2) (3)(4) compressed when bullets are loaded. To load a magazine with aremovable magazine spring retainer you can load the magazine from thebottom. To do this you must turn the magazine upside down and drop thecartridges in from the bottom. Once the cartridges are loaded theremovable magazine spring retainer is then inserted into the bottom ofthe magazine while the (5) base plate is slid over the tabs of themagazine and secures the removable magazine spring retainer. As the (3)spring compresses it applies pressure on the (2) follower and on the (4)bottom which pushes against the (5) base plate to create the counterpressure to push the (14) cartridges towards the magazine feed lips.

FIG. 2 is a view of a rifle (1) magazine which is semi loaded withcartridges. It shows how the Removable Magazine Spring retainer (2) (3)(4) which compresses when bullets are loaded. To load a magazine with aremovable magazine spring retainer you can either load the magazine thetraditional way from the top one cartridge at a time or from the bottom.To load the magazine from the bottom you must remove the removablespring retainer then turn the magazine upside down and drop thecartridges in from the bottom then re-insert the removable springretainer and compress the removable spring retainer while securing itwith the (5) base plate.

FIG. 3 displays the Removable Spring retainer which contains the (2)follower which is the top part of the Removable Magazine Spring retainerwhich pushes the cartridges up into the magazine and into the firingchamber of the firearm. The Removable Magazine Spring retainer containerconsists of 3 pieces: the (2) follower, (3) spring and (4) bottom. (3)is a view of the middle section of the Removable Magazine Springretainer, which keeps the spring contained. The Removable MagazineSpring retainer consists of 3 pieces: the (2) follower, (3) spring and(4) bottom. (4) is a view of the bottom section of the RemovableMagazine Spring retainer and sticks out past the base plate of themagazine. The bottom of the Removable Magazine Spring retainer is thebottom piece of 3 pieces: the (2) follower, (3) spring and (4) bottom.(5) shows the base plate of a rifle magazine that slides and locks on tothe magazine. The base plate locks the Removable Magazine Springretainer in place and provides the force for the spring to push againstto move the cartridges up to the top of the (1) magazine.

FIG. 4 displays the top view of the (5) base plate which is what securesthe (2) (3) (4) removable spring retainer. The (5) base plate has themiddle section removed to allow the (4) bottom to protrude out of themagazine. The protrusion allows for the (5) base plate to slide on the(1) magazine easier while the (2) (3) (4) Removable Magazine SpringRetainer is re-inserted back into the (1) magazine.

FIG. 5 displays the front view of the (2) (3) (4) Removable MagazineSpring Retainer and the (5) base plate. The (5) base plate has grooveson the inside which allows it to latch on to the grooves of the magazineand is by sliding the (5) base plate on and off. The (2) (3) (4)Removable Magazine Spring Retainer is held in place by sliding the (5)base plate onto the magazine while the (2) (3) (4) Removable MagazineSpring Retainer is inserted into the magazine.

FIG. 6 displays a view of a loaded pistol (9) magazine that contains the(10) (11) (12) Removable Magazine Spring retainer. It also shows the(13) base plate which locks in or contains the cartridges and removablemagazine spring retainer.

FIG. 7 displays a view of a half-loaded pistol (9) magazine thatcontains the elongated (10) (11) (12) Removable Magazine Spring retainerwhich pushes the cartridges up to the magazine feed lips and to thebreech of the firearm. It also shows the (13) base plate which locks inor contains the cartridges and removable magazine spring retainer.

FIG. 8 displays the compressed (10) (11) (12) removable magazine springretainer; the removable magazine spring retainer is in its compressedstate when it is inserted into a magazine with cartridges loaded andbecomes elongated when the cartridges are fired.
